We have lift off! (E73)

Russia celebrated Cosmonauts' Day on 12 April in honor of Yury Gagarin's historic flight in space, so we wanted to get into the spirit of things and see what's changed since then. On this month's cosmic special, Russia's latest space capsule promises to make spaceflight more comfortable than ever. We learn how solar wind helps us tune into our favorite show on the old wireless and a ray gun represents the latest in cutting-edge technology.
